.IMPRovEMENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 115,989, dated June 13,1871.

inventor thereof; and that the following is a full, true, and exactdescription thereof, refcr` ence being had to the drawing hereuntoannexed-that is to say- The nature of the said invention consists inconstructing apparatus for the purposes set forth, in which areemployed, in combination, a hanging or vibrating lever or frame, and aforcing rod or plunger carried and guided thereby and movinglongitudinally with regard thereto, such,motion of the rod or plungerbeing caused by its action against a cam or cams, or inclined surfaces,or other mechanical contrivances arranged to produce 'it as a result ofor from the motion of the vibrating lever.

The gures 1 to 6 illustrate an improved machine in which the forcing-rodis guided and slides lengthwise within or with regard to the lever, themotion of the rod being induced by inclined surfaces, against which thevibration causes the rod (or a roller thereon) to bear.

Figures 1 and 2 are side and front elevations, both partly in section;Fig. 3, back elevation of lever and rod. Fig. 4 is part of Fig. 3repeated, but in section, and showing varied position of rod. Figs.'5and 6 are plans at Y Y and Z Z, respectively.

a is a pillar or standard, from which lever b depends and vibrates fromthe center at c. d is a forcing-rod, guided and sliding in the lever b,which has a hollow or box-like sectional form. dX is a roller on'top vofd, and ef are inclined |surfaces on horns'projecting from the pillar,and against which the vibration of the lever (which may be moved by handor otherwise) causes the roller to bear, and thus to de press and raisethe rod accordingly as the vibration is toward or away from the pillar.g is a spring to cause the return action of the lever b. The lower endd2 of the rod and the bottom bx of the lever are intended for holdingtheperforating or other tools, and it is t0 be noted that the rod moves tovary the distance between these parts, the extent of variation beingobservable by comparing Figs. 3 and 4, and also'by comparing the dottedand full lines, respectively, in Fig. 1;- and also bycomparing thedotted arcs @"and fX in the lastly-mentioned figure. The form of thetoolholding parts may be varied, as required, for holding-tools forperforating, punching, em-

bossing, cutting, or other purpose; but as represented the said form isconvenient for holding changeable dies, such as may be used forperforating small holes disposed'to represent numeral figures or otherdevices applicable to dating or marking railway tickets. h is amouth-piece, suitable for presenting the tickets to the action of thepress. `It works on a hinge, and in use is held in position by thespring-catch i, but may be made in any other convenient manner to affordfacility for changing the dies, or may be made removable.

Figure 7 is a modification in which the form of the parts is varied, butthe feature to be especially noted is that, though the rod is de pressedby an inclined surface at e, its return action depends entirely upon aspiral spring, g', placed around it; or a spring or other suit ablecontrivance for this purpose may be otherwise applied.r Figs. B and 8ashow another modiiication, in which the action of the inclined surfacese f is obtained above instead of below the center of vibration c.

It is to be noted that the upper or forked end of rod d is perfectlyfree of the center c, for which purpose each arm of the fork has a slotor elongated opening therein to allow the sliding motion of the rod.(For placing together some of the individual members of this press theymust, if requisite, be made in pieces, A

though not so represented in the drawing.)

Another modification consists in the use of a cam-roller carried by theforcing-rod, such roller having depressed or hollow surfaces and raisedor projecting surfaces, which may, by the vibration'of the lever, bebrought to bear against a small roller on the pillar or frame, and thecam-roller may, by a ratchet motion, (acted upon by the said vibratiom)be made to turn so as to depress the rod quickly when required, andthereturn action of the rod may be e'ected by a spring or in any convenientmanner when its release is permitted by the further turning of thecam-roller.

Fig. 9 is a modification, in which the depressing-and-raising action ofthe rod isA obtained by a radius-link, It, hinged both to the rod and tothe pillar a. c is the center, from which the lever b vibrates.' Fig. 10is another modification, inwhich the forcing-rod d is hinged or hung atits upper end to the pillar a by a pin, z, somewhat near to the centerof vibration c. Fig. 11 is a detached view of upper part of lever b, andFig. 12 is a cross-section through the pin z.

In order to get in this pin it passes across through the lever b, whichhas a slotted holev to allow the required amount of play. Some amount ofplayv may also, be allowed at the lower part, where the rod is guided inthe 1ever; or the guide may be made by a fixed pin on the lower end ofthe rod7 working through slot in the lever or otherwise.

Fig. 13 is a modiiication, illustrating an up ward or an approachingmovement of one toolholder toward the forcing-rod, obtained by 1elversand rods from the movement in a downward or opposing direction of theforcing-rod itself, which is or carries the other tool-holder. The twoapproaching movements, which are simultaneous, are denoted by theopposing arrows in the figure, and similarly, the reverse movementswould be simultaneous. The object of the two movements is to dividebetween them the amount of action required for the tools. Theforcing-rod d may be putin action by or from that of the vibrating leverb in any 'of the ways herein speeied, and the approaching and reversedaction of the tool-hold ers may, if desired, be eii'ected in anyconvenient manner other than that represented.

It is evident that various modifications other than those aboveenumerated may be made, and proportions of parts may be alt-ered'without departing from the spirit of the invention, of which theforegoing description and the drawing are to be understood asillustrative only. Especially it may be observed that thefriction-roller may be placed on the pillar and an inclined surface orsurfaces be provided on the rod cl to produce the sliding action. Also,that the tool-holder at b", at the bottom of the lever, may sometimes(though perhaps not so conveniently) be replaced by one occupying aposition apart from instead of in or upon the vibrating frame. Also,that the apparatus may be arranged with the center of vibration at thebottom instead of at the top, or to work horizontally instead ofvertically, or in any direction; or may be arranged in duplicate endwiseon,77 by which expression I intend an arrangement in which theforcing-rod in each vibrating lever works in a direction approach ingand receding from the other, the ends of the vibrating levers-away fromtheir centers being those presented toward eachother. And further, insome cases it is intended to extend the vibrating lever, between pillarsor supports, to any desired with, with any convenient number offorcing-rods sliding therein, having dies and matrices acting therewith;and for convenience of working such dies and matrices they may bespecially constructed (in pieces, if desired) so as to work inaframe orcarriage made somewhat similar to aprinters composing-stick, as shownin-section at a a, Fig. 14; such frame or carriage being furnished witha separating-plate, so adapted as to allow of the free passage of thematerial to be acted on under or between the separatingplate and thematrices, as shown in Fig. 14.

Sometimes I prefer to make the dies and separating-plate in one insteadof suspending the separating-plate, when it is not necessary to pass thematerial wholly under or through the die, as in the case of datingrailway tickets and such like, where the end only of such tickets isrequired to be inserted.

a a are the frames or carriages, shown in cross-section; b, theseparating-plate; c c, the guide-pins attached thereto, and working inholes in the upper frame a, formed for the purpose; d, the die; e, thematrix; ff, the jaws of the press or apparatus for receiving the diesand matrices; m, the material to be acted on. The object of thisarrangement is for operating upon the material when in the form ofsheets or strips, which may be fed in by hand; or a feed-motion may beobtained in this ease, and also with any of the machines hereinspecified by or from the vibrating action of the lever.

It is to be observed, generally that the several varieties of themachines may be made of any size convenient to the purpose of theparticular work to be performed.

I claim- The general construction of apparatus for perforatin g, cutting, or stampin g pap er, metal, or other material in which a hangingframe is combined with a descending plunger, substantially in the mannerdescribed and set forth.`

In witness whereof, I, the said JOSEPH SLOPER, have hereunto set my handthis fourth day of March, one thousand eight hundred and seventy-one.

JOSEPH SLOPER.
